need some advice on picking two 427 engines I am looking at two different packages for a F1C ProCharger build and need help in picking the better package. I think the engines will flow about the same through the heads.
Option 1: $11700 + LS2 core
C5R block
Lunati LS1 4" Crank
Lunati Pro Billet Rods
Diamond or Weisco pistons
Stage III hand ported 243 heads
FAST intake
Jesel sportsman rockers
Option 2: $11000 - no core exchange
LS7 block
Eagle crank
Compstar rods
Diamond or Weisco pistons
Stage III CNC ported L92 heads
L76 intake
L92 rockers
Option 1: $11700 + LS2 core
C5R block
Lunati LS1 4" Crank
Lunati Pro Billet Rods

I know the sky is the limit, but I was trying to stay on a budget and figured that I could upgrade to a FAST L92 should it hit the marktet later on or sell the L92's and upgrade to a LS7 top end should the fund become available. Option #2, seems like the least expensive way to build a reliable motor capable of handling 800hp.
I guess the real question is - is the C5R/Lunati/Lunati kit worth the extra dollars over a LS7/Eagle/Compstar? I would expect the two listed top ends to flow about the same.

Option 1 seems to be a better platform of those two. What are your goals though? IMO you can build a stouter engine than either of those for less cost. Start with an LSx block, which is already a third of the price of the C5R block, and use roughly the same components.
